STRAW-CUTTER.

Specification forming part of Letters Patent No. 43.459, dated July 5,1861.

To all whom it may concern Be it known that I, DARoY PORTER,'0fCleveland, in the county of Cnyahoga and State of Ohio,have invented newand useful Improvements in Hay and Straw Cutters; and I do herebydeclare that the following is a full and complete description of theconstruction and operation of the same, reference being had to theaccompanying drawings, making part of this specification, in which-Figure l is a perspective view, and Fig. 2 is a vertical longitudinalsection.

Like letters refer to like parts in the several drawings.

My invention relates to such a construction that the bottom board of thecutting-box moves up and down to correspond with the motion of themoving knife.

Arepresents the stationary part of the frame, and B representsstationary side pieces of the straw box.

C represents the bottom board, which is mounted upon spring-boards D E.

F represents the stationary knife, which is secured to the stationaryframe A. The moving knife F is secured to the sliding crosshead G, whichis operated by means of the lever G. Upon the inside of the crosshead Gis a pressure-board, a, which is attached to the oross-head and moveswith it. This is bevelid upon the under side to freely admit the raw.

H represents a feed-roller, the journals of which are in the sidepieces, B. It is operated by a pawl and ratchet, as shown at I. Thespringboard E can be graduated to different degrees of pressure by pinsE.

In the operation of this machine the straw is pressed between the bottomboard, C, and the pressure-board a, and is fed to the knife by the pawland ratchet, as shown in Fig. 2. Every downward stroke of the lever Gcarries with it the cross-head, bottom board, 0, and straw, giving thespurs on the feed-roller a new hold upon the straw. The length of thecut is regulated by a stop-plate, J, in front of the moving knife. Thisplate is adjustable by placing it in different grooves, as shown at b bin Fig. l.

What I claim as my improvement, and desire to secure by Letters Patent,is-

1. The arrangement and combination of the springs D E,bottom board, C,knivesE and F, and feed roller ll, for the purposes herein set forth;

2. In combination with the above-named parts, the adj ustablc plate J,for the purposes described.
